Ifitweretoraintomorrow,wewouldputoffthesportsmeeting.
Ifheshouldnotcometomorrow,weshouldputoffthemeetingtillnextMonday.
①错综时间条件句:
当条件状语从句表示的行为和主句表示的行为所发生的时间不一致时,被称为错综时间条件句,动词的形式要根据它表示的时间作出相应的调整。
如:
Ifyouhadfollowedmyadvicejustnow,youwouldbebetternow.
Ifyouhadstudiedhardbefore,youwouldbeacollegestudentnow.
②if省略句
在条件句中可以省略if,把were,had,should提到句首,变成倒装句式。
IfIwereatschoolagain,Iwouldstudyharder.
→WereIatschoolagain,Iwouldstudyharder.
如果我还有上学的机会,我会更加努力学习。
Ifyouhadcomeearlier,youwouldcatchthebus.
→Hadyoucomeearlier,youwouldcatchthebus.
如果你来得早点,你就能赶上公共汽车。
Ifitshouldraintomorrow,wewouldnotgoclimbing.
→Shoulditraintomorrow,wewouldnotgoclimbing.
如果明天下雨的话,我们就不能登山去了。
③用介词代替条件状语从句
常用的介词有with,without,butfor。
Whatwouldyoudowithamilliondollars(=ifyouhadamilliondollars)
如果你有100万元,你会做什么?
Wecouldn’thavefinishedtheworkaheadoftimewithoutyourhelp.(=ifwehadn’tgotyourhelp)
没有你的帮助,我们不可能提前完成这项工作。
Withoutyourhelp,wecouldn’thavefinishedtheworkaheadoftime.
=Butforyourhelp,…
=Ifithadnotbeenforyourhelp,…
=Haditnotbeenforyouhelp,…
④含蓄条件句
有时在虚拟语气中并不总是出现if引导的条件句,而是通过其他手段来代替条件句。
Iwasillthatday.Otherwise,Iwouldhavetakenpartinthesportsmeeting.(副词)
Hetelephonedtoinformmeofyourbirthday,orIwouldhaveknownnothingaboutit.(连词)
Amanwhostoppeddrinkingwaterwouldbedeadinaboutsevendays.(定语从句)
Imighthavegivenyoumorehelp,butIwastoobusy.(连词)
Everythingtakenintoconsideration,theywouldhaveraisedtheiroutputquickly.(独立主格结构)
⑤evenif,eventhough也可用于虚拟语气,其形式与if从句在虚拟语气中的形式相同。
